To all whom it may concern:

lle it known that we, FRANK J. TniPLn'r'r and lliLmAM N. TmPLE'r'r, both citizens of the United States, residing at Maxwell, in.

the county ot Colusa and State of California, have' invented new and useful Improvements in Harvestcrs, of which the following is a specification.

Our invention relates to improvements in combined harvesters.

.ltconsists in the combination and ar rangement of parts and in details ot construction which will be more fully explained Ihy reference to the accompanying drawings,

in which- Figure l is an elevation of our machine viewed from the header side. Fig. l is a separate view ofthe header and dra per driving mechanism transverse to Fig. 1. Fig. 2 is a side elevation of thcmachine from the opposite side to Fig. 1, Fig, 8 is a longitudinal vertical section corresponding t0 Fig. l. Fig. l is a transverse section of a grain and straw separating riddle. Fig. 5 1s a plan view ot the apparatus.

lt is the object ot our invention to proI y vide an improved apparatus for harvesting]-` grain, including' the cutting, transferring trom the sickle to the threshing cylinder, threshing, separating the threshcd straw and grain, delivering the grain. to cleaning screens, and discharging the straw, and s0 onstrlwting these parts that the machine mayv he very much shortened, the weight hrought more completely upon the main hearing wheels, from which .power is dej rived to drive the lnachinery and in the lop cation ot the threshing cylinder approximately in line -ahove the bearing-wheel shafts; and 1n such general economy of the driving chains as-to greatly reduce then` lengt-h with a consequent improvement in their maintenance and wearing qualities.

.ts we have here shown. the exterior easing .t is mounted upon the timbers Q which are framed together in the usual or any suitahle manner to provide a bearing for the ditierent parts ot the apparatus. The transverse timbers of the frame extend upon each side of the main frame, and form openings within which the hearing and driving wheels 3 and 4 are journaled and turnable. In the present drawing, these Wheels are shown with plain surfaces, but it will he understood that they may be provided with raised plates, termed grousers to linsure a sutiicient' traction to prevent the wheels from slipping, and to insure motion being transmitted to drive the various parts, depending upon the motion of these wheels. The main portion of the weight is so bal` anced upon these hearing-\vl1eels that they will he most effective in developing and transmitting the necessary power. The front end of themachine is carriedl upon the caster-wheel 5 which is readily turnable to follow the movements of the machine as it is swung from one side to the other, and We are enabled to dispose with the heavier wheels and the horizontal circles in which such wheels are usually turnable thus considerably reducing the expense of the appaatus, and increasing the convenience of its operation. The header so-called projects from the right side, near the front of the machine (only ay small portion of itis shown as at and the sickle travels in the usual sickle guard as at 7, and is reciprocated by a crank 8 upon a shaft 9. The elevating ripper 10 ,extends upwardly at an angle from the inward end of the header, and carries the grain upwardly and delivers 1t into the feed-house at the front end of the casing A, where it falls upon an endless traveling helt 11, and by this belt is delivered to the threshing cylinder. yThe reel 12 journaled above the front portion of the header, serves to sweep the grain inwardly to the sickle, in the usual manner, and itis mounted upon a tiltable frame or arms as at 13, hy which ,it may be raised or depressed to suit the height and character of the grain to be cut. These deyices do not fmaterially differ vfrom those in common use in this class of mechanism, but it is in the location of the threshing cylinder, the balance ot the parts, and the manner of transmitting power to drive the various moving parts that `our invention particularly lies.

The cylinder 15 is of the usual or any suitable type journaled and revolublc nearly in line vertically above the line of the hearing-wheel shafts,.and the concave, so-called, whichconsists of a series of teeth between which the teeth of the cylinder revolve, and through which the .straw is carried to break up the heads and separate the grain therefrom, is located above the cylinder, as shown at 16. The carryingbelt 11 upon which the straw is delivered from the header is thus made of considerable length from the t'ront back to the center of the machine. The upper portion of it passes below guideplates 17 projecting over each edgel so that this upper portion of the belt is turned slightly upivard -just before it delivers its load to the threshing cylinder. Above the inner end of this belt 11 is a second belt 18, 'passing around suitable bearing-drains and converging toward the inner endof the belt 11 and the cylinder 15 so that the straw will be regularly and evenly fed to the cylinder, and being carried through the concave le by the-rapidity of motion and moment-um or' 'the cylinder, will be very thoroughly Separated. From the cylinder and concave the straw and rain are discharged upon 'an upwardly anrgl rearwardly inclined traveling belt '19. -`Between the upper and lower portions of this Slat belt 19 are disposed vertical plates 20 Which forni a riddle or grizzly, the plates forming this device being suihciently .separated so that grain may pass between them, and falling upon the direction-board 21 the grain will be delivered upon the front end of the uppermost of the screens 22, upon which the grain is cleaned in the usual manner.

23 are pickers, socalled, ovewhich the straw is lifted as it passes over the upper end ofA the belt 19, and being thus loosened most of the remaining grain Will be separated therefrom, and carried to the cleanv ing shoe.

24 is an open Slat straw-carrying belt upon which the straw is received, and it' there still remains any grain, it will fall through this belt and upon the screens vwhich are located below it, the straw being delivered out -at the rear end of the machine in the lilsual manner. t 1 The grain` passin through the screens is received and trans y'erred to one side ofthe machine by 'a revoluble grain-carrying auger l25, and the tailings are discharged from the outer rear enti of the machine, and are received andtransported in like manner by -anauger 26.- These angers deliver the grain to endless traveling elevators Within 'the cases' 27 and E28 respectively, one carry ing the grain to a point Where it will be' delivered through a chute 29 to the sacking deyiee,vplainly shown in Fig. 2; the other returns any lunthreshed heads and delivers 4l.- is a sprocket-Wheel 81. A sprocket-chain 32 passes over this wheel. both above and below, converging forwardly over a small sprocketavheel 38, and at the rear end it comerges over another' sprocket-Wheel 34, the lower portion of the chain passing also overl an idler 35 located between the main driving sprocket 31, and the sprocket 34 so that by reason of the smaller diameter ot' the two sprockets 233-34, and the interposition of the idler 35, the chain 32 is caused to Wrap i'ar enough around the driving sprocket 31 to insure power being transmitted to the chain suilicient for all purposes to Which it will be subjected. The sprocket 83 is n'iounted upon a shaft 36 Which extends transversely across the machineto the opposite side, and is provided at this opposite end With. a bevel-pinion 37 which engages a corresponding pinion 38 upon a longitudinally journa'led shaft 39. Upon this shaft is a sprocket-pulley aroufnd which passes ak chain 40, and this chain extends across to the right sideof the machine to drive the header mechanism. At this point it passes around a pulley 41, thenceup- Wai'dly over a pulley 42 mounted upon a shaft at the upper end of the elevator draper,

and through this it drives the draper l() so as to deliver the grain from the sickle t'o the thresher ris-previously-described; thence passing backwardly and around a sprocketpulley 113, it returns to the sprocket upon the shaft 39 at the opposite side ofthe ma- I chine. The sprocket 43 is mounted upon a' shaft 9 which, as previously described, i1n parts motion to the sickle.,I Thus all this imechanism is driven by a single chain. 'The object in first transferrinp)f the power from` *the* right to the left side o 'the machine, then returning .it through the long sprocket-cha in, ie to make this chain solong that the movements of the header mechanism, when it is raised or depressed to cut high or low grain,

will have little or no etiect in lengthening or shortening the driving-chain,'since the arc oiiniovementat thatehd `is so slight that the chain will substantially maintain its tension whatever change may take place in the position of the vertically movable parts.

The rear Asprocket 34: around which the main chain 32 passes is mounted upon a shaft-,fivhich carries a sprocket-Wheel dei.

upon inner end and near to the side of the nuichine casing. Around this sprocket'- 'wheel l*passes a chain 45, thence around a sp1ocketwlieel at 46. Upon the shaft of this wheel- 46 isv another sprocket around which passes" a chain 47, This chain passes over sprockets upon the shafts 48 and 4t2) respectively, of the elevators, thence returning to the sprocket on the shaft4 4to, fand through vthis chain both the elevators are driven.' Upon the opposite side of the ina'- ing-Wheels, and an automatically turnable front caster-Wheel upon which the frame is borne, a spi'oclet-wheel carried by the right beariiig-wheel, a sprtvcltehpinion, 'a header and chains through which motion is transmitted to drive the header, a second spiocket-\vlieel carried by the left hand bearing-Wheel, sprocltet-pinions and connectu ing' chains whereby the motion of one of said sprocketq'iinions is reversed with respect to aiiother, an internal' gear and a shaft by which said sprocket-Wheel is connected With said gear upon the right side o t the machine, a threshing cylinder and a pinion upon the threshing cylinder shaftwhereby said cylinder is revolved in a. direction opposite to that of the bearing Wheels, said cylinderbeing disposed in a vertical plane passing through the axis of the main bearing-Wheels, and a concavedisposed above said cylinder and co-acting therewith.
